AP22683893 " The technology of processing Kazakhstan's hard–to-enrich vanadium-containing ores by hydrometallurgical method to obtain the target product, vanadium pentoxide (V2O5)"

Relevance

The project is relevant due to the need for efficient processing of Kazakhstan's hard-to-enrich vanadium-bearing ores. Traditional methods do not provide sufficient extraction of vanadium due to its complex mineralogy. The development of hydrometallurgical technology using electrochemical oxidation will make it possible to involve previously untapped reserves of strategically important metal in processing.

Purpose

The aim of the project is to develop a technology for processing Kazakhstan's hard-to-enrich vanadium-containing ores by hydrometallurgical method, providing for the conversion of the hard-to-open part of vanadium-containing minerals into a soluble form using electrochemical oxidation, leaching and precipitation of vanadium pentoxide (V2O5).

Expected and achieved results

A laboratory unit for anodic oxidation of vanadium has been launched. The chemical and mineralogical compositions of vanadium-containing ores have been studied. The scientific novelty of the project is to obtain new data on the electrochemical oxidation of vanadium-containing ores in the anode space (phase ratio W:T, sulfuric acid concentration, current density, duration) and the development of a hydrometallurgical technology for processing vanadium-containing ores from the Balasauskandyk, Kurumsak and Jabagly deposits by electrochemical oxidation to extract vanadium into solution.
